Connections

Hardware unit: Drehbank

Front panel

• 64 control knobs

• 64 labelling pads (for the user to label t he function of each control knob).

• 3 switches (on the left side of the unit; black):

-

(one) to create a „Snapshot“ (the top switch)

-

(two) to switch from one bank to the ot her ( the lower 2 switches) (5)

• 3 L.E.D.s, one above each switch which indicate: (4)

-

When a 'Snapshot“ is being sent

-

Midi events

-

Which of t he t wo banks is in use

Back panel

• 8 external control inputs (optional) (6)

• Power input connection (1)

• Midi Ports

-

MIDI-In (2)

-

MIDI-Out / Thru (Merge) (3)

Power input/ Power supply (1)

The

Drehbank

is powered by an external DC power supply. A 230V power supply with
Euro plug is included in the package. For count ries with different voltages or plug socket s
you’ll have to buy the appropriate power supply in your country (9V DC@250mA output
required). On the unit t her e is no O n/Off switch. So to turn the unit on and off you have to
connect / disconnect the power cable. Alternativly we recommend using a multiple mains
socket with an On/Off switch.

Midi-Out-Buchse (2)

Drehbank Page 4 Short Manual

Connect the MIDI-OUT of the Drehbank with the MIDI-IN of the device you want to
control with the Drehbank.

Midi-In-Buchse (3)

The Drehbank merges the Midi data coming into the Midi In port with the generated
data of the respective control knobs. The complete merged data is then sent to the
Midi Out port.

Note:
Drehbank normally works in Midi Merge mode.

Important:

If there is a lot of data coming into the Midi In port it is possible that the Drehbank
will have problems with merging, as the internal me mory has a limited capacity.
When transferring a lot of Midi events we recommend the use of an external
merger.

The Drehbank editor and the Drehbank communicate via Midi. This requires a
sound card with Midi interface or a special Midi card that works with the Windows
multimedia driver (e.g. the Unitor from Emagic). You can configurate the Midi In and
Out ports through the Windows menu titled Multimedia/Midi.

Note

Please take care that you don’t create Midi loops, because the PC could crash!

To avoid creating loops we have built in the option to deactivate the merg e m ode in 3 steps (
found in the editor program ).

Control-LED's (4)

The L.E.D.s are on the left side of the unit, one above each switch.
They indicate the different oper ation modes and actions of the

Drehbank

.

Operation indicators

When the

Drehbank

is switched on all 3 L.E.D.s light up and stay lit for about 5 seconds.
In this time the data fr om t he non-volatile memory (EEPROM) is transfered to the work
buffer (RAM, volatile memory) of the unit. When t his is com pleted the L.E.D.s switch off and
the L.E.D. that indicates bank 1 lights up, as bank 1 is then active. If this does not happen
then either the power input is not correctly connected to the

Drehbank

or it‘s possible that

the plug or the

Drehbank

has a defect.

Bank indicators

The indicators show which bank is active:

-

L.E.D lit over Bank 1 (Bank 2 off) indicates BANK 1 is active.

-

L.E.D lit over Bank 2 (Bank 1 off) indicates BANK 2 is active.

Short Manual Page 5 Drehbank

Snapshot Mode

Once the snapshot switch has been pressed the L.E.D. above it blinks r apidly. By pressing
the switch once again within a second a „Snapshot“ will be sent and this is indicated by the
L.E.D staying lit (again f or about a second). After this the L.E. D.s returns to bank indicator
mode.

Midi events Indicator

Under normal operating the L.E.D. which indicates the Snapshot mode is switched off. For
that reason this L.E.D. ( top ) is also used to indicate Midi events.
The L.E.D. flashes f or every activity on the Midi bus (both Midi In, and Midi Out).
Midi events are normally performed very quickly and therefor e t he flashing of the L.E.D. is
hardly noticeable. Turn a controller and watch the g low of the L.E.D.
The indicator also shows if a control knob is sending an event. Also you can see, if the

Drehbank

is receiving Midi data.(e.g.the receiving of information from t he editor program.)

Switches (5)

On the left of the unit you`ll find 3 black switches with the following functions:

Recalling the original settings/ Rom p resets

As you will see the Drehbank unit has no ON button/switch. To activate the ROM presets
you must press a switch at the same time as you plug the power In (see the README.TXT
file).
The indicator above the pressed switch will not light up, but instead the ot her two indicators
will flash.
E.g., when turning the unit on you press switch 1 (the top switch), to select ROM preset 1.
The L.E.D. above that switch will not light up, but t he other 2 L.E.D.s will light up. This
inverted indication system also goes for the recalling of the other presets.

This means that the Drehbank at that m om ent loads the ROM preset and will wait until you
release the switch.
After this the Drehbank returns to normal operation mode and switches to bank 1, the
L.E.D.s are now also in normal operation mode.
Now the Drehbank is ready to ROCK. ☺

The recalling of the ROM presets has no effect on the nonvolatile memory (EEPROM). The
preset that you loaded from the editor software into the nonvolatile memory still exists. To
activate it again you must turn the unit off and on again.

Switching between the 2 banks

For each bank there is one switch and one L.E.D. indicator.
Simply select a bank by pressing either of the bank switches on the Drehbank

.

The
Drehbank will then activate the selected bank, which is indicated by the flashing of t he
L.E.D. above the pressed switch.

Creating and sending a Snapshot

To create a Snapshot you must first pr ess t he t op switch (labelled snap) . When the switch is
pressed for about a second the L.E.D. ( that is otherwise inactive except for Midi activities)
blinks rapidly. Press the switch again within a second and a Snapshot will be sent, indicated

Drehbank Page 6 Short Manual

by a long flash of the L.E.D. This flash is important, because if you trigger a Snapshot
accidentally ( or at the wrong time) you could overload the Midi connection.
Once the Snapshot has been sent the Drehbank returns to bank indicator mode.

Important

If you change your mind and don‘t want to send a Snapshot (or if you go into the
mode by accident) just wait until the L.E.D. stops blinking, (after one second)

Remember

A Snapshot sends the controller values of all 64 knobs from the active bank.

External control inputs (6)

If you have a unit fitted with the optional external contr ol inputs, you will find the 8 external
inputs at the rear of the unit ( labelled external inputs)

The 8 external inputs are assigned to the following control knobs;

8 64 Foot controller

Non volatile memory / presets

When you turn on the

Drehbank

without going into the editor program you’ll find several

complete presets already available.
These are:

-

The Fixed ROM Presets, which are found on the EPROM, with the operation sof tware of
the

Drehbank

, but this can only be altered by updating the EPROM.

Note:
The layout of ROM preset 1 is printed in the appendix. Information on ROM presets
2, 3, and 4 is found in the README.TXT file. (on the CD)

- The Changeable non-volatile EEPROM Preset. This pr eset is located in the internal

non-volatile memory (EEPROM) and will under normal operating conditions be loaded int o
the work buffer (RAM).

Software Drehbank Editor

Short Manual Page 7 Drehbank

On the CD you will find some editor program s for the Drehbank:

Installationshinweise

:

Informations about the programs you will get on the CD in the respective heading which you
can reach over the list of contents in 'Start.html'.
For that simply double-click the intall-file in your browser.
Then you could install the program direct form the browser or make a copy on your hard disc
an start the file for m your har d disc.
The installation will then suggest you a default pat h ' \programme\doepfer\dr ehbank\V1_1' or
for the SoundDiver '\progr am me\emagic\doepfer\soundDiverOEM', where to copy the
program and data files. This default path you can change if you want.

Windows PC Editor Programm

Once you‘ve installed the application you’ll find a file titled Drehbank.EXE in the directory
you have chosen.
You can also create a link on the desktop for quicker access to the editor application. To
start the program simply doubleclick on t he Drehbank.EXE file.

System requirements

The Drehbank Editor is a Windows application which requires the following system

• IBM compatible PC .

• CPU > 90 Mhz (recommended)

• > 8 Megabyte RAM (recommended)

• > 2 Megabytes of free space on the hard drive/disc.

• Windows 3.x, Windows 9x, or Windows NT.

• VGA Monitor with a resolution of at least 640x480.

• MIDI Interface (e.g. soundcar d with MIDI Int er face).

• Multimedia Midi cable to connect the Drehbank.

• 3.5“ floppy drive or InterNet connection.

• Drehbank.

The editor program also works without a Drehbank, because the program needs no
feedback from t he Drehbank.

Warning:
Before you install the editor program (Please) read the README.TXT(help) file.

Emagic SoundDiver Doepfer OEM-Version

The CD contains an Adpation and an OEM-version of the Emag ic SoundDiver ( With this
OEM version you could only use Doepfer Adaptions).

This could be very interesting alongside an existing

Drehbank

editor as those of you who
work with the SoundDiver won‘t have to switch to a new editor program. Above all it gives
Macintosh users the possibility to edit their

Drehbank

without having to buy a P.C.
